SouthNorway, I don't have the data you request but do have the experience and you can easily work up loads. First, cast bullets will be superior to jacketed bullets. next, medium to light bullets work best. Next, a powder burning rate that is fast and will be consumed in the bbl. will reduce noise. The longer the bbl. the better. That would be pistol or shot gun powders that are forgiving of excessive air space in the case. I had fun with this all the way down to a .32cal round ball in a 8mm Mauser with bullseye powder. You only hear the firing pin in the best case and will usually be quieter than an air rifle. I first became interested in this because of shooting CB caps in a .22 rifle with a long bbl. as a teenager and found it was quieter than my pellet rifle with twice the impact. You can duplicate this in larger cals. Hope I helped. Tomygun

Thanks Tomygun, thats helpful. The reason for subsonic loads is because I go hunting close to populated areas, and I dont want to piss off anyone by firing a 30-06 close to people. I was wondering about getting a silencer, and wanted subsonic rounds for the 308 and 30-06 so I could go totally silent. I`ve heard about bad prescission because of turbulence inside the cartridge due to the low amount of powder inside, but what Tomygun suggests could really work. Although I was thinking that it would be best to get a heavy bullet, like 220 grains for the 30-06, and get it as close to the sound barrier as possible. Guess that would be about 1000 fps, or 340 m/s because we use the metric system in norway.

I just got that Savage acu trigger sweet, .308 and I'm fixin to work up some loads myself. I came on here to get some ideas. I reloaded some 308's a long time ago but it was for a Model 100 Win , and it got stolen years ago. I was using some 150 PSP factory and shot a tight group at 100 yds at the range. As soon as I find out what works good I'll come back and tell it.

SouthNorway, Your thinking is correct. If your intent is to hunt large game silently you will need a silencer and restrict your velocity to about 1050fps at less than 1000ft. elivation. This being said then the heavier 200 to 220gr. bullet should suit you. A powder such as blue dot or the like should do what you wish. Don't wory about air space in the case but test what you load. Depend on impact and penitration rather than expansion when selecting a bullet shape. Expect a trajectory similar to a .22lr and practice with it. It works for the military and should also for you. This little explored area of rifle shooting has the most to offer. Best of luck Tom

Hi, does anyone have reloading data for subsonic ammo in 308 or 30-06? Or experience with these kinds of loads?

If my memory serves me right I beleave 11 grains of Trail boss and a 180 bullet works,I looked for my paper work but its like everything else I put in a safe place and now I forgot where the safe place is.

I have some reduced recoil loads using Blue Dot Pistol powder with a 150 grain Remington SP bullet for my 30-06. I was originally informed of these loads by Seafire (a member of this forum) and consequently tried it myself and found the data to be sound.

Start watching for pressure signs with 25 grs of Blue Dot and consider 26 grs the maximum load.The Blue Dot powder is exceptionally well suited for reduced loads. It is a high volume to weight ratio powder which ignites easily and consistently. I use Winchester large rifle primers. There is no need for fillers with these reduced loads.

I did some experimenting with SR4759 for reduced loads but was not impressed. I believe the Blue Dot powder is better suited for this scenario.

I have used the Blue Dot for reduced .243 loads (with exceptional results) and for my 30-30. I am considering working up a reduced load for my .257 Wby Mag also using Blue Dot powder.

Thanks for the info. The load that I use for the 170grn lead gas check in my 30-06 requires a filler. So I wanted to try the blue dot and get away from using the filler (mom get mad when I steal her pillow and quilt stuffing)

You also said that you used it on the 243. could you give some of that info or atleast a good place to start

ThanksDS28
